Amanita Phalloides Poisoning

Death Cap Fung Caus Tox Effct

Amanita phalloides poisoning is the most common form of mushroom poisoning. These mushrooms contain the poison amatoxin that affects primarily the liver and leads to disturbances in gastrointestinal and renal function, seizures, coma and death.

The clinical manifestations of poisoning by amatoxin may be grouped into four phases.

The first phase is a period of latency, with the onset of signs and symptoms delayed until 6 to 24 hours. In some instances, patients do not present until 2-3 days after mushroom consumption [1].

The second- or gastrointestinal- phase is marked by patients developing abdominal pain, vomiting and severe diarrhea that may contain blood. The fluid loss may progress to hypovolemia, electrolyte disturbances and circulatory shock [2] [3]. The levels of liver enzymes and bilirubin are usually normal at this stage.

In the third phase, patients experience a gradual resolution of dysentery over a 24-hour period, suggesting an apparent recovery. However, elevations in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) become evident at this stage, with jaundice clinically apparent in some individuals.

Abstract Intoxication due to eating wild mushrooms presents with a variety of signs, ranging from mild diarrhea to severe organ failure.[ncbi.nlm.nih.gov]

The initial symptoms of nausea, vomiting, abdominal pain and diarrhea, which are typical for the intoxication, can be interpreted as a common gastro-enteritis. The intoxication can progress to acute liver and renal failure and eventually death.[ncbi.nlm.nih.gov]

The following findings emerged: vomiting (76%), diarrhea (62%), hepatic failure (24%), and renal failure (11%). Two patients died on the fifth day after mushroom ingestion.[ncbi.nlm.nih.gov]

All persons who consumed the mushrooms developed nausea, vomiting, and diarrhea approximately 9 hours after ingestion.[cdc.gov]

Methods Case Four women, living together in a convent, were admitted because of nausea, vomiting and diarrhoea. Symptoms started approximately 10 hours after eating wild mushrooms, self-picked in the forest.[gut.bmj.com]

These mushrooms cause self-limited nausea, vomiting, diarrhea and stomach pain. The onset of symptoms is rather rapid (0.5 to 3 hours).[missouripoisoncenter.org]

Within 6 to 12 hours after eating the mushrooms, violent abdominalpain, vomiting, and bloody diarrhea appear, causing rapid loss of fluid from the tissues and intense thirst.[britannica.com]

In the second stage, which is about 24 hours long, the patient will typically experience abdominalpain, vomiting, and bloody diarrhea. The third stage is again about 24 hours. During this period, the patient appears improved and recovered.[sinaiem.org]

The toxins initially cause severe abdominalcramping, vomiting, and watery diarrhea, and then lead to liver and kidney failure.[encyclopedia.com]

She returned to the ED the following day with persistent nausea, vomiting, diarrhea, and abdominalcramping. At that time, her AST was 1,712 IU/L, ALT 1,025 IU/L, total bilirubin 2.0 mg/dL, and INR 1.8 units.[cdc.gov]

The electrocardiogram disclosed sinus tachycardia. Aggressive treatment with fluids, activated charcoal, penicillin G and silibinin were started. The patient was sent to hemodialysis because of anuria.[ncbi.nlm.nih.gov]

Jaundice, hepatomegaly and neurological symptoms were not present, but liver enzymes were moderately increased. Alfa-amanitin was detected in sera of all patients.[ncbi.nlm.nih.gov]

Intoxication symptoms usually appear after a latent period and may include gastrointestinal disorders followed by jaundice, seizures, and coma, culminating in death.[ncbi.nlm.nih.gov]

The chemical nature of the toxin has not been determined, but it is a source of monomethylhydrazine, which affects the central nervous system and induces hemolytic jaundice. Get unlimited access to all of Britannica’s trusted content.[britannica.com]

Microscopic hematuria may be present in the initial stages of poisoning, whilst acute renal failure may manifest as proteinuria and gross hematuria. Oliguria and anuria may be the other findings.[symptoma.com]

Death caps are also easily confused for a variety of edible fungi--and they are spreading throughout North America, and other continents. Let's hope that silibinin , which is derived from the plant milk thistle, can make a difference.[popsci.com]

The diagnosis of Amanita phalloides poisoning relies heavily on the accuracy of the various clinical findings and must be suspected in individuals presenting with a late onset of gastrointestinal symptoms coupled with hepatotoxic signs.

A complete liver profile may help document the hepatic injury caused by amatoxins. This includes aspartate transaminase (AST), alanine transaminase (ALT), serum bilirubin, alkaline phosphatase (ALP) and lactic acid dehydrogenase (LDH) levels. A coagulation profile measuring the prothrombin time (PT) and activated partial thromboplastin time (aPTT) is a reliable marker for mushroom intoxication and hence, should be measured routinely.

All patients with suspected ingestion of amatoxin-containing mushrooms must undergo certain baseline investigations including measurement of serum electrolyte and blood glucose levels, and a complete blood count [7]. Creatinine and blood urea nitrogen levels may be raised, especially in renal failure.

Microscopic hematuria may be present in the initial stages of poisoning, whilst acute renal failure may manifest as proteinuria and gross hematuria. Oliguria and anuria may be the other findings. Pancreatic amylase and lipase levels need to be measured as well.

Imaging studies in the form of abdominal X-rays, ultrasonography or a computed tomography (CT) scan may help to narrow the differential diagnosis. Histology of liver specimens shows centrilobular necrosis accompanied by areas of hemorrhage and necrosis.

The presence of amatoxin in the suspected mushroom samples may be detected via the Meixner test. The high number of false-positive cases with this test impairs its usage in a clinical setting. The spores of the implicated mushroom may be examined in gastric secretions, appearing smooth and turning blue on exposure to Melzer solution. Other tests used to measure the level of toxins include high-performance liquid chromatography, thin layer chromatography and radioimmunoassays [8].

RESULTS: Six patients, with mean age of 46 years (range: 9-70 years), underwent one to three ECAD treatments. The mean time from mushroom ingestion until the first ECAD treatment was 76 h.[ncbi.nlm.nih.gov]
